Prime Meridian
A prime meridian is an arbitrarily chosen meridian (geography), meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. On a spheroid, a prime meridian and its anti-meridian (the 180th meridian in a degree (angle), 360°-system) form a great ellipse. This divides the body (e.g. Earth) into hemispheres of Earth, two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Prime meridian (Greenwich), Greenwich Meridian, the previous standard. Longitudes for the Earth and Moon are measured from their prime meridian (at 0°) to 180° east and west. For all other Solar System bodies, longitude is measured from 0° (their prime meridian) to 360� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bering Sea
The Bering Sea ( , ; rus, Бе́рингово мо́ре, r=Béringovo móre, p=ˈbʲerʲɪnɡəvə ˈmorʲe) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and the Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named after Vitus Bering, a Denmark, Danish-born Russia, Russian navigator, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Berin ...

List Of Antarctic Territorial Claims
Seven sovereign states – Argentina, Australia, Chile, France, New Zealand, Norway, and the United Kingdom – have made eight territorial claims in Antarctica. These countries have tended to place their Antarctic scientific observation and study facilities within their respective claimed territories; however, a number of such facilities are located outside of the area claimed by their respective countries of operation, and countries without claims such as Spain, China, India, Italy, Japan, Pakistan, Russia, South Africa ( SANAE), Poland, and the United States have constructed research facilities within the areas claimed by other countries. There are overlaps among the territories claimed by Argentina, Chile, and the United Kingdom. History Spanish claims According to Argentina and Chile, the Spanish Crown had claims on Antarctica. The ''capitulación'' (governorship) granted to the conquistador Pedro Sánchez de la Hoz in 1539 by the King of Spain, Charles V, explicitly ...

Ross Dependency
The Ross Dependency is a region of Antarctica defined by a circular sector, sector originating at the South Pole, passing along longitudes 160th meridian east, 160° east to 150th meridian west, 150° west, and terminating at latitude 60th parallel south, 60° south. It is claimed by New Zealand, a claim mutually accepted only by Australia, the United Kingdom, UK, France and Norway, which are countries that also have territorial claims in Antarctica. Under the 1961 Antarctic Treaty System, Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". The Dependency takes its name from James Clark Ross, Sir James Clark Ross, who discovered the Ross Sea and includes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ʻEua
ʻEua is an island in the kingdom of Tonga. It is close to Tongatapu, but forms a separate administrative division. It has an area of , and a population in 2021 of 4,903 people. The island leads in agriculture, tourism, and some of the forestry helps the island economically. Geography ʻEua is a hilly island, the highest peaks are the ''Teʻemoa'' (chicken manure) 312 m, and the ''Vaiangina'' (watersprings) 305 m. The island is not volcanic, but was shaped by the rubbing of the Tonga Plate against the Pacific Plate, pushing ʻEua up and leaving the Tonga Trench on the bottom of the ocean, a short distance towards the east. The soil of ʻEua is volcanic, as is that of Tongatapu, but only the top layer, deposited by eruptions of nearby volcanoes ten thousands years ago. Under it are the solid rocks of pushed-up coral. ʻEua counts many huge caves and holes, not all of which have yet been explored. ʻEua and Niuatoputapu are the only islands in Tonga that have stre ...

Tongatapu
Tongatapu is the main island of Tonga and the site of its capital, Nukuʻalofa, Nukualofa. It is located in Tonga's southern island group, to which it gives its name, and is the country's most populous island, with 74,611 residents (2016), 70.5% of the national population, on . Tongatapu is Tonga's centre of government and the seat of its monarchy. Tongatapu has experienced more rapid economic development than the other islands of Tonga, and has thus attracted many internal migrants from them. Geography The island is (or including neighbouring islands) and rather flat, as it is built of coral limestone. The island is covered with thick fertile soil consisting of volcanic ash from neighbouring volcanoes. At the steep coast of the south, heights reach an average of , and maximum , gradually decreasing towards the north. North of the island are many small isolated islands and coral reefs which extend up to from Tongatapu's shores. The almost completely closed Fanga'uta and Fa ...

Tofua
Tofua is a volcanic island in Tonga. Located in the Haʻapai island group, it is a steep-sided composite cone with a summit caldera. It is part of the highly active Kermadec-Tonga subduction zone and its associated volcanic arc, which extends from New Zealand north-northeast to Fiji, and is formed by the subduction of the Pacific Plate under the Indo-Australian Plate. It lies about above a very active seismic zone.Ewart, A.; Bryan, W.B.; and Gill, J.B. "Mineralogy and Geochemistry of the Younger Volcanic Islands of Tonga, S.W. Pacific." ''Journal of Petrology.'' 14:3 (1973). It is connected to the nearby island of Kao by a submarine ridge. The island is a national park. Geography and geology The island is oval, measuring approximately 80 square kilometers. Its sides rise steeply to the rim of the caldera, which is partially filled by a volcanic crater lake with a depth of . The caldera was formed by a major eruption around 1,000 years BP, which left deposits up to thick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kao (island)
Kao is an island and stratovolcano in the Haʻapai island group of Tonga. It lies about north of Tofua island and reaches above sea level, the highest point in Tonga. The date of its last eruption is unknown. Although Kao does not display fresh-looking lava flows, it is likely very recent in origin due to the absence of deep gullies or high sea cliffs. The slopes of the island rise at angles exceeding 35 degrees to the summit, which has a series of small volcanic craters. The last reported eruption was on July 10, 1847. The best access to Kao is by small boat on the south coast of the island, although heavy swell can make this treacherous and a skilled boat coxswain is required. There are no permanent paths to the summit. Small areas on the lower slopes are cultivated by kava growers. The island is densely jungled on its lower flanks, interspersed with thick chest-height ferns that are virtually impassable to all but the most determined trekkers armed with machetes and a good ...

Alaska
Alaska ( ) is a non-contiguous U.S. state on the northwest extremity of North America. Part of the Western United States region, it is one of the two non-contiguous U.S. states, alongside Hawaii. Alaska is also considered to be the northernmost, westernmost, and easternmost (the Aleutian Islands cross the 180th meridian into the eastern hemisphere) state in the United States. It borders the Canadian territory of Yukon and the province of British Columbia to the east. It shares a western maritime border, in the Bering Strait, with Russia's Chukotka Autonomous Okrug. The Chukchi and Beaufort Seas of the Arctic Ocean lie to the north, and the Pacific Ocean lies to the south. Technically, it is a semi-exclave of the U.S., and is the largest exclave in the world. Alaska is the largest U.S. state by area, comprising more total area than the following three largest states of Texas, California, and Montana combined, and is the seventh-largest subnational division i ...
